Can My Mac Be Infected By Computer Viruses?

Of course, Macs are safe computers, and they are even safer than Windows devices. Anyway, it doesn’t mean they are fully protected from malware. Apple devices are usually attacked by PUP and adware.

However, these protections are not perfect, so users should still stay cautious when downloading apps or browsing the web. It is useful to know how to check for malware on Mac with different methods, since built-in protections might miss some threats.

What Are the Signs When a Mac Has Malware?

When your Mac has malware, you can notice several signs to tell you about it. Here are the main symptoms you should pay your attention to if you suspect malware and want to check for malware on Mac:

• Your device behaves weirdly and launches programs or open windows without your command.
• Your computer runs too slowly without many apps working on it like the processor is busy with something.
• You notice weird adverts very often.
• You see some unknown apps or programs you haven’t installed before.
• You see an application that asks to type the administrator password.

Removing Malware from Your Device Manually

If you have found a malware infection on your computer, don’t worry, it’s not so difficult to delete it without any damage. Follow the next steps for how to check for malware on Mac and remove it effectively:

1. Remove your browser’s extensions. Often, malware can come like browser extensions. That’s why we suggest viewing your browser’s extensions thoroughly. If you see some weird extensions you never installed, feel free to remove them. These are malware! This is especially important if you use browsers like Safari, Google Chrome, or Mozilla Firefox.
2. Sometimes, malware can be disguised as legitimate software. That’s why it’s quite important to download programs only from well-trusted sources. If you have downloaded an app from an unknown site, it’s better to get rid of it immediately! Whenever possible, download applications from the official Mac App Store or from trusted developers.
3. Check your installed applications and remove any suspicious apps you do not remember installing. It is also helpful to review running processes in Activity Monitor and look for unknown programs that consume unusual system resources.
4. Make your login item clean. Sometimes, malware can sneak into the login items of your Mac. Clean them up to prevent launching: go to System Settings, choose Users and Groups, and then click Login Items. Use buttons with “minus” and “plus” to manage them simply.
5. Advanced users can also check common macOS locations where malware sometimes installs automatic startup files, such as the LaunchAgents and LaunchDaemons folders in the Library directory.
